Cryptography is an indispensable tool for protecting information in computer systems. In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two parties generate a shared secret key. Throughout the course participants will be exposed to many exciting open problems in the field and work on fun (optional) programming projects. In a second course (Crypto II) we will cover more advanced cryptographic tasks such as zero-knowledge, privacy mechanisms, and other forms of encryption....

A really interesting and in-depth course. It is pretty challenging and requires good math/proof skills, but still quite fun. The course could use more study materials, for example lecture notes.

Really interesting, provides the basic grounds for understanding a lot of discussions out there. Wikipedia can be useful as a reference, but here I was able to learn about semantic security etc.

Very comprehensive overview of Cryptography. Though a bit too mathematical for me, the gist of it is very helpful to understand cryptocurrency protocol design of Bitcoin, Ethereum, Monero...

Excellent course. I've worked with cryptographic methods and practice for many years, but this course provided me with a stronger understanding of the underlying theory than I'd had before.

Great grounding of the cryptography basics, but does require a decent understanding of basic computing (bits, XORs) and some reading on finite field maths beforehand would definitely help.

Great Instructor, really enjoyed his style of expanding the math "sentences" into lay English EVERY SINGLE TIME! That really helped this learner "go with the flow" as my background is CS.

The course gives fundamentals of Cryptography. But I would say that it dig very deep with fundamentals so I would highly recommend this course if you need/want to understand Cryptoraphy

Great into to the disciple for those of use who are interested in it but don't have access to a formal crypto class for what ever reason. This class made me fall in love with Coursera.

It was an amazing experience. This course was suggested by my mentor to allow me to get in depth knowledge in cryptography. The course conveys all the latest protocols and mechanisms.

Very well explained. I am also reading some research papers, it has become very easy to understand what they are talking about. One must read the additional material for good results.

Great introduction to the concepts. I really enjoyed learning everything in this course. My only regret is that I was too busy to take time to do the optional programming assignments.

Very good lecture. I learned a lot about cryptography and basic ideas about security. I just hope Dan speaks slowly from next lectures. Definitely will take Crpytography II as well.

Excellent course, with lots of theory and real life exemples. Be prepared to dedicate a lot of time and effort to pass this course. One of the best and hardest I took from any MOOC.

Excellent explanation on the concepts of cryptography. The course gradually builds the concept from the basics. The graded assignments are beautifully designed to test the concepts.

This course is f**king difficult!!! But if you're a software engineer, you definitely need this course to make sure that you're using the right algorithm to protect your softwares.

Definitely the most interesting course I've taken on Coursera. Great material, very well presented. I recommend doing the optional programming assignments, they're a lot of fun.

awesome! It takes some time for me to understand some concepts and I need to pause a lot when watching the video, thus it may take you more time to study than the estimated time.

amazing course, i take it 6 years ago and forget everything, but again,learn crypto, like meet a familiar new friend, feel enjoyable with what professor Dan Boneh have taught me

Loved this course.... Dan Boneh is clear, and covers amazing subjects that were not perfectly for me before attending the course (RSA, DH...).

Great job and thank you very much !

Excellent course to master the basics of cryptography, and for smart card developers to understand what's written in the specifications. Crytpography II is my next goal :-)
